WOOD-FIRED BOILERS - Fuel Efficiency, LLC

Wood burning boilers however, normally create considerable ash and soot build-up in the firetubes, resulting in inefficient heat transfer and a loss of steam pressure. Most wood-fired boilers require manual tube brushing. This means shutting down the boiler for hours while mill personnel brush the ash build-up from the firetubes.

Therefore a 25kW wood log boiler would heat a volume of 1500l in approx 3-4 hours (a typical operation period for log boilers). From the above we would normally size an accumulator tank at approx 55l per kW of boiler input. Wood Pellet Boiler. Wood pellet boilers differ from log boilers, in that they can modulate accoding to the heat load.
